Appetite- Wanting to eat EVERYTHING

So this has been going on consistently for about two months now. My appetite has been crazy! πŸ˜œπŸ‘πŸ‡πŸ’πŸ§€πŸ³Β 
I'm eating throughout the day without feeling full. And screw portion sizes! I've been eating almost twice as much as my man (unless he's secretly eating a bunch at work/with friends and not telling me). I feel like my hunger never ends. When I'm not eating an actual meal, I'm snacking on something. Or looking to snack on something.Β 
I'm NOT overweight. I'm petite and often get told I'm underweight but not unhealthy. I haven't been gaining any weight during all of this. A little bloating here and there but I've maintained my thin figure while intaking all this food.Β 
At this point I'm just wondering why on earth I'm so hungry all the time! Maybe I just love food and it's my vice? πŸ€”Β 
Today was the day I got off my period, don't know if hormones have a play... But this has been going on continuously so probably not Β
